METALLIC PLATE Foa FACING WALLS.

SPECIFICATION forming part of Letters Patent No. 358,1'75dated February 22, 1887.

Application tiled June 5, 1886. Serial No. 204,200. (No model.) Patented in England December is, i870, No. 5,095, and in Germany June 3 To all whom it may concern:

Be it known that I, PHILIP ALEXANDER THOMAS, of Nash Mills,V Hemel-Hempstead, county of Hertford, in the Kingdom of England, and a subject of the Queen of Great Britain, have invented a new and useful Im provement in Metallic Plates for Facing or Covering Structural Surfaces, (the said invention having been patented by me in England [o by Patent No. 5,095, dated December 12, 1879, and in Germany by Patent No. 11,698, dated June 3, 1880;) and the following is a full and true description thereof, reference being had to the accompanying drawings, which form I5 a part of this specification.

My invention relates to the joining together of the individual plates which form the sheathing or covering, and to the means by which they are secured to the structure to be covao ered; and it has for its object the union of the plates in such a way that their joints shall be unobtrusive to the eye, tight and impermeable to water, and at the same time conceal and protect the nails or other fastenings by 2 5 which the plates are secured to the wall, roof,`

or other structure.

Reference being now had to the drawings which illustrate my invention, Figure 1 is a lview of a hexagonal plate made in accordance 3o with my invention; Fig. 2, a view of two of my plates of square outline, showing the manner in which they are united and secured to the structure to be covered; Fig. 3, a sectional view on the line m m of Fig. 2, andFig. et a similar section showing another method of securing the plates to a plaster or concrete back- Ing. 7

A A A2, die., are the faces or exposed sur'- faces of my plates, which must be of a sym- 4e metrical outline and either four or six sided.

The outline of the plates having been determined on, the blank is cut out, leaving on one half of the adjoining edges an excess of metal sufficient to form the S-shaped fold and projecting flange B, while on the remaining half the excess of metal is equal to the depth of the fold on the edge B, and forms a tenon or tongue, C, which can be inserted in the B fold. These edges C are preferably bent as shown,

when the plates are to be used for ornamental 5o purposes.

To prevent the edges of two adjoining folds, B, from overlapping, I prefer to cut off the corners of the metal anges, which in the blank project beyond the face of the plate.

The plates are secured to the roof or wall by nailing or screwing them thereto by means of the projecting'iianges of the folded edges B. One or more plates having been thus secured, the tongues or tenons C of other plates 6o are inserted in the fold B, covering its flange, and this plate having been nailed down the process is continued until the whole structure is covered, each plate being at each of its edges interlocked with another plate, and each securely fastened to the supporting structure represented by D in Figs. 3 and 4.

Where a wall or other surface to be covered is made of or covered with plaster or a like substance, I prefer to secure my plates 7o thereto in the way shown in Fig. 4. A hole is cut in the plaster, and in it is inserted a bent strip of metal, F, which is secured therein by filling up the hole with cement Gr. The projecting end of the strip F is then bent down and inserted in the S fold of one of the plates, (see, for example, B4, Fig. 4,) the tenon O of the other plate being inserted in the same fold. As will be seen, the lplates are thus securely hooked to the strips F, when, as is of 8o course usually the case,the B folds of the plates are its lower edges.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. As a new article of manufacture, metal plates for covering structural surfaces having a plain equilateral outline of four or six sides, half of the adjoining sides being provided with S-shaped' folds and half with straight flanges 9o or tenons,substantia1ly as shown and described, so that each plate may be interlocked at each of its sides with another of similar outline and separately secured to the structure to be covered.
